Characteristics

This software is not a virus or a Trojan. It is detected as a "potentially unwanted program" (PUP). PUPs are any piece of software that a reasonably security- or privacy-minded computer user may want to be informed of and, in some cases, remove. PUPs are often made by a legitimate corporate entity for some beneficial purpose, but they alter the security state of the computer on which they are installed, or the privacy posture of the user of the system, such that most users will want to be aware of them.
